Application filed January 1S, 1311.

T all whom. it may concern.'

Be it known that l. TiioMAs F. WELSH, a citizen of the United States, and resident ot' Boston. in the county of Suffolk and State ot' Massachusetts.have invented an linprovement in Looms with Automatic Fnsitive Shuttle-Drives and Shuttle-Changers t'or Heavy loi-k, or' which the following description. in connection with the accompanying drawings. is a specification, like characters on the drawings representing like parts.

My present invention provides a positive drive for the shuttle capable of handling practically any character of filling, Wire, cane. or otherwise. and weaving the same in practically unlimited widths and preferably with an uninterrupted Weaving movement. in connection with anautomatic shuttle changer adapted to sucli heavy work.

ln the preferred embodiment of my invention. as herein shown, the shuttle is carv ried bythe lay and has a positive racli and pinion drive. The shuttle is shorter than the width ot' the fabric. and. to permit this rack and pinion drive under such circumstances. l have devised a special reed or warp-defiecting mechanism for deflecting the warp threads which form one side of the shed. preferably the top thereof, so as to permit the coperative engagement of the shuttle with its driving mechanism in the midst ot the fabric.

ln connection with the above mechanism, l provide automatic means for supplying the large shuttles with their heavy load of yarn. cord. rope. wire. or so forth, said supply mechanism and a cooperating discharge mechanism preferably operating at predetermined intervals. depending upon the character of the filling and hence the amount or length thereof which it is practicable for one shuttle to carry.

The constructional details of my invention will be pointed out more at length in the course of the following description, considered with reference to the accompanying drawings. which illustrate one of the preferred embodiments of the invention.

ln the drawings, Figure l is a central vertical longitudinal section ofthe loom; Fig. 2 is a right hand end view thereof; Figs. 3 and 3 are views thereof in front elevation, parts being broken away and omitted; Fig.

in the preferred construction of my present loom, as herein shown, the shuttle 1 traversed or driven on the lay 2, which is supported and swung by usual lay swords 3 pivoted at 4 between the side frames '5, 8, said lay swords being shown as swung by lay connectors 7 pivoted at 8 on cranks or crank wrists 9 adjacent the end frames on a shaft driven hy mutilated gears 11, 12, the former on said shaft and the latter on the main drive shaft 13. [is herein shown, eachsliuttle 1 is provided on its upper rear edge with an upstanding rack har 14 extending the length of the shuttle in position to he engaged by gears iournaled in a cap or support 16 secured to the upper end of the lay swords above the reed 17, which is secured to said cap by screws 1S. The gears 15 may he driven hy any suitable power transmission mechanism, preferably carried hy the cap support 16. 31s herein shown, on the front ends of the shafts 19 of the gears 15 aietoothed pinions 2Q meshing with the teeth cfa reciprocating reels oar 21 I mounted in a guideway 22 at the front over4 of the fabric.

hanging portion of the top or support 1G. This rack is operated by a link Q3 pivoted thereto at24, Fig. 3a, and piyotally connected at 4to a lever or arm 26 pivotally mounted at 27 on the right hand end of the pivoted shaft 4 of the lay swords. A link Q8 is pivotally connected at Q9 to said arm 26 and at 30 to a crank or arm 31 extending upward from a rock shaft journaled at its opposite ends in bearings or brackets 33 extending inwardly from the lower end of the end frame 6. said rock shaft 32 being provided at its rear end with a. cam lever 34 whose roll 35 is actuated by a path cam 36 fast on the cam shaft 37. The gears 15 are spaced apart across the loom at intervals commensurate with the length of the shuttle, the loom herein shown having four of such gears, two at the ends iustl outside of the width of the fabric and two in the midst ln order to permit these intermediate gears to be thus located and to engage the rack 14 of the shuttle, provision is made for separating or detlecting the. top warp threads of the shed so as to provide a gap to be occupied by the adjacent gear 15. Preferably this separating or detlecting of one of the horizontal walls of the shed is accomplished by means of the reed (or whatever means is provided for beating up), although lit will be understood that the separating function and the beatingeup function are entirely distinct and the mechanisms are therefore to be considered distinct.y

As best shown in Fig. 4, it will be seen that the lower part of the reed has the dents or wires 3S vertical and parallel to a sutilcient height for beating up the warp threads 39 when leveled, but that said reeds are out of parallel and bent obliqnely away from the middle of the section, as indicated at 40, the innermost reed ll-1 being herein shown as Y-shaped and open at its upper end a suflicient distance to compel the warp threads to b e suliciently deflected so as not ,to interfere with the gear 15, or in other words, this arrangement of thc dents or wires of the reed compels the normally parallel warp threads to be deflected out of parallel on the shedding movement and open a gap in thejtop of the shed at the point occupied by a gear 15, there being as many sections of reed similar to that shown in Fig. 4 as there are gears 15 in the midst of the fabric. rl`hus gaps are formed by de-- ileeting the warp threads in the wall of the shed which is adjacent the shuttle operating gears Whenever the shuttle is to pass through, but the warp threads are all maintained straight and parallel in usual manner during the beating up step of the weaving, and this alternate straightening and defleeting of the warp threads takes place for every cycle of Weaving operations and is ac- 'ing-up to their shed position, although it will be understood, as already stated. that the gap forming mechanism or wari'i-thread detlecting mechanism, is .not to be confused with tlie-reed proper, and that a separate or independent mechanism for this purpose is within the spirit and scope of my invention.

. As herein shown, I have provided simply an ordinary two-harness sheddingmechanism. similar harnesses lf2, 43 being herein shown supported by straps 4st, 45 passing in opposite directions around a shaft-4G at the top of the loom, said harnesses brune connected respectively by lam shafts 4l', 4S linked to their lower ends, and straps i12), 50 connecting to usual treadle levers 51, pivoted at 53 to a fixed support and actuated by cams 51, 55 on the cani shaft 37. T he warp threads pass through the harnesses in usual manner from let-oli' rolls oiI tension rolls .36, .3T t0 the fell at 5S and thence over a breast beam 5U to a take up roll'GO, and guide rolls o1, 62 to any kind of a \\'inding mechanism, not shown. v l

The gear shuttle is shown in Figs. G-S, where it will be seen that it consists of a large rectangular box-like receptacle for the cop, the leading end of whose thread passes through an eye 63 in the inner end of the shuttle and thence through an eye oft in the front wall to and through an eye (35 at about the middle oi' the shuttle. In view of the size and weight of this shuttle when loaded with its complement of yarn, wire, or other heavy material, thc lay 2 provided with transverse roller bearings GG to raise the shuttle above the warp threads at the bottom of the shed so as to Vprevent the shuttle from` catching' against any of said warp threads or' injuring said threads, and also so as to give the shuttle free easy movement as it is traversed by the rack .and pinion driving mechanism. The reed acts as a guide for the rear side of the shuttle, and at the front side of the lay I provide a series of short guides or guards 67 for preventing the shuttle from moving forward from its proper course. As herein shown, the lay extends beyond the end frames of the loom. the right hand end thereof being provided at its rear side with a stationary guide plate G8 and the left hand end thereof with a front guide plate 69 and a rear guide plate 70. These two plates G9, 70 are vertically inorable in connection with the shuttle chang-Lg mechanism, as best shown in Fig. 1. The front guide plate 69 is connected by links 71 to crank arms 72 extending forwardly from a rock shaft 73 provided with a rearward arm or lever Tel which'connects by a rod 7 5 to an intermediately pivoted arm 76 actuated at its rear end T7 by a cam TS fast on shaft 79. The rear plate T0 is similarly connected by links S0 to crank arms S1 on a shaft S2 provided with a lever S3 connected by a rod S1 with an intermediately pivoted lever S5 whose roll S6 is actuated by a cam 87;

At a suitable place with reference to the operating shuttle, preferably at the left side of the loom outside of the end frame 5, is a shuttle remover and chute, the latter being herein shown in the form of an inclined shelf or platform SS having a stop 89 at its lower end, and the former being shown as two rearwardly extending arms 90 provided with hooks 91 and pivoted at 92. A lever or rocker arm 93 entends forward to an actuating rod 91 for actuating said arms 90, said rod being operated by an intermediately pivoted lever 95 whose cam roll 96 is actuated by a cam 9'." on the shaft 79. The lay 2 is provided in its upper side, at either end of the plates 69, 70, and in alinement with the hooked arms 90, with transverse slots or openings 98 for receiving the hooked arms 90 at each forward beat of the lay, said arms, however, accomplishing nothing when in the position shown in Fig. 1, but only when moved from that position by the cam 97 for discharging a spent shuttle. When therefore a shuttle has been exhatsted, the front plate 69 is moved down out of holding position with relation to the shuttle by its cam 78, and, the lay then being in its forward position, the cam 97 causes the hooked arms 90 to be lifted slightly so that their ho'oks 91 engage behind the spent shuttle 1, discharging the latter, which slides down the chute S8, on which it is retained by an end flange 99. The timing of these cams is such that, when a shuttle has been shot across the loom the predetermined number of times suited to its capacity with the kind of filling being woven, the shuttle will be discharged. The spent shuttle having been discharged, a new shuttle and supply of filling is inserted on the backward movement bf the lay, so that when the lay has come to a halt, the new shuttle is already in place ready`to be shot forward without any interference with the continuous weaving operation. For this purpose, the rear guide plate T0 is moved down by its cam S7 as the lay is swinging back, and at the same time the front plate 69 is moved up.

Pivoted at 100 on a projecting end of a stationary supporting bracket 101 is a pair' of supports 102 projecting forward in the form of relatively narrow thin fingers to enter the slots 98 on each backward swing of the lay, and projecting rearwardly at 103 to receive the forward new or fresh shuttle from the feed chains or shuttle carrier 101` as said carrier is moved along at the proper time by its actuators. The shuttle carrier 101 for supplying new shuttles .as needed is herein shown as mounted on sprocket wheels 105 at its opposite ends actuated by a Geneva movement, the star wheel 106 of which is engaged by a pin 10T of a pin wheel 10S on the hub of a sprocket wheel 109 driven by a chain 110 and sprocket wheel 111 fast on the shaft T9 driven intermittingly by any suitable mechanism. As herein shown, a mutilated driving gear 112 i's .fast on the Cam shaft 3i', see Figs. 13. 1l. and drives ar gear 1123 splined for longitudinal movement on vthe shaft T9 and moved into and out of crank 119. sleeved on a stud on said end frame, controlled by a dog 121, Fig. 1, riding on the peri phcry of a cam 122 fast on a stub shaft 123. The shaft 123 is driven by a dog 124: engaging a ratchet 125 on said shaft, said dog being actuated by a rock bar 126, rod 127, and cup crank 12b fast on a shaft 37. At one side of the cam wheel 122 is a locking plate or dwell wheel 129 against which a dog 130 is held by a spring 1231. ln theperiphery of the cam 122 is a cam depression 132 which permits the dog 121 to be actuated by the spring 115, thereby throwing the gear .113 to the left, Figs. 3 and 125. which starts the shaft 79 so as to throw out the spent shuttle and put in a new one. The shuttle carrier 101 is spaced apart the width of the shuttles by front guides or holders 33 and rear holders 134. ligs. 1, 11, 12. which extend up rigidly from the links of the carrier chain in position to hold a shuttle between them. The uprights 12S-1 also serve as pushers for delivering the shuttle.

Preferably the holders 1321 on the inner chain next to the end frame 5 are provided with spring clips 135 to receive and bind the free end of the filling yarn of the `shuttle so as to hold the same back as the shuttle moves.

permit them to be readily delivered to the supporting arms 103. Asher-ein shown, the shaft 37 rotates once only for two picks or shots of filling, so that the ratchet 125 is advanced one tooth for each complete to and fro movement of the shuttle, so that the shuttle is necessarily always on the changing end of the lay (as herein shown, and preferably, at the left hand end of the loom).

After the spent shuttle has been removed by the hooked arms 90 on the forward swing ot' the lay, as already described, the arms 102 enter the slots 9S as the lay swings back, the plate having meanwhile been drawn down out of the way, as previously described, and a new shuttle has been advanced from the chain onto the arms 103 and then shoved along by the pusher uprights 134, which continue to engage said shuttle until its rear side has been pushed to the position indicated by the free end of the upper oblique pusher 134-, Fig. 1, whereupon the shuttle is engaged by the front inclined edges 136 of shuttle placers or positioning' plates 137 raised at this moment by bars 138 mounted to slide in a stationary bracket 139. The lower ends .of these bars 13S are held fast in a transverse bar 140 actuated by a link 14.1 and bell crank lever 142 pivoted at 143 on the frame, whose cam roll 14sL is actuated by a cam 145 on the shaft 79. AAs the placer plates 137 rise to shove the fresh shuttle into accurately placed position on the lay, it is necessary that said shuttle should be slightly lifted in order that it may properly ride up onto the rolls 66,

and accordingly I provide a cam surface 146.

on the upper rear edge of each plate 137 to engage a stud or roll 1el-7 on the adjacent arm 102, whereby, as said shuttle placer rises. its cam surface 146 operates against the adjacent stud or roll 147, to swing the arm 102 on its pivot 10() so that. said arm is lifted just enough to permit the lay 2 and its rolls 66 to ride back under the shuttle as the shuttle is being pushed forward to meet it.

To position the shuttle accurately endwise (rendered advisable because of the rack and pinion drive for the shuttle). I provide an overhanging endwise director or guide 14S whose ends flare outwardly toward the rear or are bell shaped as indicated at 141-9. 150. Fig. 3, the rear upper edge thereotI preferably also flaring as indicated at 151, Fig. 1. This bell shaped or tiaring housing' or endwise positioner. compels the shuttle to aline itself with the utmost accuracy end wise and also prevents any tendency whatever to be' tipped or rolled by the placer plates 137. Sti'il further to insurf.` certainty of proper engagement between the racks 1+i and their driving pinions 15. I bevel or round ofi'A the ends of their teeth 1:12, as shown at 153. Figs. 9 and 10. thereby providing a flaring or bell shaped spare 154 between each pair of teeth of one member to receive the wedge lshaped or sloping and pointed ends of the teeth of the other member. as the shuttle is slid sidewise into position on the lay, thereby bringing its rack 1li into interlocked relation with the end gear 15. This peculiar form of teeth and intervening spaces is only necessary for those portions 'of the end Crear and the front end of the shuttle rack viiiich are subjected to said sidewise engagement when a new shuttle is put in place. The result is that as the lay comes into its rear position, the shuttle has arrived in operative position thereon and the rear plate or gate 70 is then raised into position to cooperate with the front plate 69 to guide the shuttle accurately as it is moved forward by its rack and pinion moving mechanism. As soon as the placers 137 have performed their positioning ottice, they drop back out of the way of the next shutte. rI`he rolls 66 are preferably arranged at sufficiently short distances to bring enough of them under a shuttle at one` time to prevent any possible unevenness of `travel of the latter and the shuttle is slightly upturned at. the ends of its bottom as indicated atl 155 for still further facilitating the smooth running thereof on the rolls.

To insure that the spacing of the front and back guide plates 69, 70 shall remain always the same, I preferably secure to the woodof the lay front and back metal plates 156 to receive the wear of the up and down movement of the plates 69, 70, which are slotted to ride on lugs or vertical guide strips 157 secured to and projecting from said plates 156. Cap plates 1.38 are bolted over said slots to said strips 157, thereby forming with the latter T-guides for the slotted plates 69, '70. The loom is driven by va'belt 159, Fig. 2, and pulley 160 on the shaft 13 (the starting and stopping being under the usual control of a shipper handle 161 and lever 162) and gears 163, 164. v

In lhandling certain kinds of warp material. it is advisable to have the gap or warp deflection less than in Fig. L1, which is better adapted to relatively loose or coarsely' woven fabric. In Fig. Q2, I have shown a reed aii'ording a smaller gap, and in Fig. ll one showing a still smaller gap. In the former instance, theraclr and pinion mechanism is substantially the same as already described. excepting that the driving pinion smaller, as shown at 165, Figs. 21, 22 In the latter instance, I have shown a still smaller gizar 166, Figs. Q3, 21, whose shaft 167 carries a pinion 168`at its forward end meshing with a gear 169 on a shaft 170, to whose outer end is secured the pinion 20, already described. driven by the racl 21 mounted in the cap support 16.

IVhile I prefer the form of shuttle shown in Figs. 6-8, it will be understood that the shuttle used in practice conforms to the filling material being woven, and while the shuttle 1 is adapted to a wide range of tilling materials, it is not adapted to all the heavy work which my loom provides for.

It will be understood from the foregoing description that my invention provides positively driven means for traversing the shuttle'vvith a uniform speed irrespective of Whether the 'lling material is light or heavy, readily tiexible or stift, small or large, even or bunchy, smooth or rough and kinky, Weak or strong. Also, notwithstanding this strong positive driving mechanism, preferably carried by and operating in connection 'with the lay, the construction is such that it is entirely practicable to operate the loom at a relatively high speed as compared vvith previous looms for such work, and the shuttle changing mechanism furthermore accomplishes the discharge ot the spent shuttle and placing of the fresh shuttle Without requiring the stopping or slowing dovvn of the loom.

By positively actuated or positively driven, I mean to distinguish from a. shuttle Which is simply shot across the loom by an initial impulse and then le'it to take care of itself by its ovvn momentum. This is the movement and operation given to what is lrnovvn as a ily shuttle, which is impelled b v a sudden severe blov.'r from a picker stick` the result being that the yarn is brought under extreme snapping strain at the beginning of the movement, which movement is extremely rapid at the start and diminishes as the shuttle proceeds across the loom. My shuttle drive is distinguished from this, by having a continuous and uniform driving impulse imparted thereto throughout the entire traverse, by thel direct and continuous wagement With the shuttle of driving or moving means throughout the entire travel A., the shuttle from one edge of the fabric the other. This eliminates all sudden stain upon the filling, and makes it possible to Weave at relatively high speed such irregular, bunchy, kinky, stitt' material as is frequently used in Weaving jute bagging, for instance. Wvhon, therefore, l refer in the claims to positively actuated or positively driven shuttle,A l mean to restrict the same to the operation and mechanism as thus defined.

Having described my invention, what I claim as neu' and desire to secure by Letters Patent is:
